Timbren 2001 Sterling Truck Acterra 5500 Rear Suspension Enhancement System

The Timbren RED001 Suspension Enhancement System uses a unique rubber spring technology, a design choice that has been a hallmark of the brand since 1965. This system is specifically built for the rear suspension of a Sterling Truck Acterra 5500, particularly those equipped with Reyco/Freightliner rear suspensions that have over 5 inches of clearance. It's designed to work with your existing suspension, acting as a helper spring to absorb road shocks and provide a more stable ride, especially when towing or hauling heavy loads.

Unlike air spring systems, Timbren's rubber cushions require no airlines or fittings, meaning there's nothing to leak and no ongoing maintenance beyond the initial bolt-on installation. This makes them incredibly easy to use and maintain, offering a lifetime of trouble-free operation. The system automatically adjusts to uneven loads or road conditions, helping to eliminate vehicle squatting and sagging that can occur when your truck is under stress. This improved stability can lead to better handling and a greater sense of peace of mind when you're on the road with a heavy trailer or cargo.

Installation is straightforward, typically requiring only basic hand tools and no drilling or routing of airlines. The system is designed to fit right into place, making it a practical solution for enhancing your truck's load-carrying capabilities and overall ride quality. With a substantial 17,200 lb weight capacity, this system is a solid option for those who frequently tow or haul, providing added safety and confidence.
